Is unused infrastructure capacity in the inner suburbs all used up?

There was more evidence in The Sunday Age on the weekend that the spare infrastructure capacity that is widely presumed to be available in the inner city and inner suburbs has in all likelihood already been consumed.

What is unfortunate about this stubborn idea is that there are already sufficient good reasons for increasing housing density in established suburbs without having to resort to unsubstantiated and outdated beliefs.

Proposed 520 unit development, Coburg. How much 'spare' infrastructure capacity will it use?

New research by Professor Kevin O’Conner, Melbourne University, shows that the number of additional students who will be seeking enrolment by 2016 in the inner city and inner suburbs is equivalent to fourteen new schools.

However existing schools are generally at capacity. The principal of Port Melbourne primary is reported as saying “schools in this area don’t have the capacity to cope with more students….looking at my projected enrolments and those of neighbouring schools, and from what I hear about the plans for extra multistorey developments in Southbank and Docklands, we will be full soon”.

He could’ve mentioned that virtually every school within at least 10 km of the CBD already has one or more so-called temporary class rooms including, now, the two story portable, and some are using public parks for play and sport.

Unfortunately there is no credible contemporary analysis of infrastructure capacity and costs in different parts of Melbourne. As I’ve argued before (here and here), there is unlikely to be significant spare infrastructure capacity in the inner established areas. There are a number of reasons for this proposition: Read the rest of this entry »


Spare infrastructure capacity – is it a tall story?

Here’s more evidence that claims of “spare” infrastructure capacity in inner city and inner suburban areas are a tall story. The Sunday Age reports that Port Melbourne Primary School, Malvern Primary and Middle Park Primary are the first schools to get double storey portable classrooms.

Two storey portables are a natural evolution – practically every State primary school in Melbourne within 10 km of the CBD already has single storey portables. However I’m not concerned with whether portables are better or worse than permanent buildings but rather with what additional classrooms say about spare capacity in schools.

As I argued previously in Why ‘spare infrastructure capacity’ is exaggerated, it is a mistake to think that there is necessarily spare infrastructure capacity just because an area historically had a higher population than it has at present. Read the rest of this entry »


Why ‘spare infrastructure capacity’ is exaggerated

Are claims of spare infrastructure capacity in the inner suburbs real?

The Age reports that there were almost 30,000 more people living in Coburg and Pascoe Vale in 1976 than there are now (The Outer Limits). The paper quotes the former Mayor of the City of Moreland, who says that increasing the population density in many areas “is simply returning suburbs to previous population levels”.

The editorialist in The Age of 20 March stated that “some ‘traditional’ inner Melbourne suburbs – such as Coburg, Pascoe Vale and Fitzroy – have fewer residents than they did 50 years ago. Current ‘in-fill’ housing is thus regrowth” (emphasis added).

The idea of course is that there is spare capacity in infrastructure and amenities that can accommodate ‘restoration’ of the historic population level. This would be a good thing because any underutilisation of infrastructure is economically wasteful. It might also minimise further ‘sprawl’ at the urban fringe. Read the rest of this entry »
